' atented June :1913.

Serial No. 519,337.

To all 107mm. it may concern Be. it known that t, Jenn E. Gmson, acitizen of the United States, and resident of Port \Vashington, in thecounty of ()zaukec and State of \Vifseonsin, have invented certain newand useful In'iprovements in Ilarvesters; and I do hereby declare thatthe following is a full, clear, and exact description thereof.

My invention consists in what is herein particularly set forth withreference to the accompanying drawings and pointed out in claims, itsmain object being to insure the operation oi the n'iaehinery of anordinary harvester when ground conditions are such that the main-wheelot' the harvester cannot perform its function as a driver for saidmachiiuwry; this object being attained by employing a motor (preferablya gasolene engine) of suitable power in clutchcontrolled gear connectionwith the aforesaid l'nachinery, the motor being mounted upon atruclcthat has universal-joint eonneetion with the rear of the harvesterto eom 'iensate for irregularities of surface over which said harvesterand truck are traveled and thus prevent cramp in the gearing by whichsaid motor 'and'the harvester machinery are connected.

Figure l of the drawings represei'its a plan view of a trailer truck .inuniversal.- joint connection with the main frame ot an ordinaryharvester, a motor in the form of a gasolene engine mounted on the trueand clutchcontrolled gearing connecting the crank-slnrt'ts of the motorand harvester; Fig. 2, a partly sectional elevation o't' what is shownin Fig. 1, as viewed from the side; big. 3, a partly sectional view ot adetail of the me hanism lllt'licittetil by line FJ--3 in Fig. -t-. andsaid Fig. 4, a similar view indicated by line t t in Fig. 3.

lieterring by numerals to the drawings 5 indicates the rear sill of themain frame, and o the crankshaft of an ordinary harvester rean y foroperator-controt of power transmission from its main traction-wheel, Tto said crank-shaft. that. is provided with .a sprwitetwhcel torengagement with an elevator driveehain. not shown.

ts shown in Fig. l, the power transmissin!) gen immprises a.spreehot-wheel fast. or. the main shaft constituting an axle rigid intin"; main wheel 7; a link-belt CUltl" ot' a spanner lover (not shown)Convenient to the operator-ct the machine. lllowever any suitable powertransmission gear under operator control may be employed. I

Embracing the sill 5 are clips 9 having split-thimble extensions 10 atright-angles thereto. The arms of each clip are bolted together underthe sill 5 and a clamp-screw 11 is employed in connection with each clipto bind against a side of said sill. The thimlilo-extension 10 of eachclip is tightened on a stem 12 by means of a bolt and nut, the bolt; 13'being extended through cars 14: with which said thimble is provided. iClip ends 15 oil a horizontal bar ltt are tightened on the stools 12 bymeans of bolts and nuts, each of said ends of the bar being providedwith cars 17 through which the corresponding bolt. 18 is passed, andfrom the foregoing it. will be understood that; the bar 10 may beadjusted on said stems to vary distance between said hi and theharvester frame, as occasion may require for the alineinent 0t link-beltand sprocket-gear hereinatter more particularly speeitied.

The bar It) is provided with a hushed center hearing ti) tor ahorizontal shank ex tension 20 ot a vertically tll l3t j0tl bow Q1, anda bore ot the bow and its shank is also hushed, the respectiveanti-'l:'riction bushings 2;, 2 being shown in Fig. 3. Extending throughthe bushing :23 is a spindle it last at one end, in a l)()r'tl" ..1ll.'pinion :25 and at the other end in a sprocket-whccl 2(5, a spacingcollar 27 being interposed between the hub of the sproclcct-wheel andthe bushing A link belt con ects the sprocket whccl era with a similarwheel 2*. that is in one piece with or otherwise rigidly connected tothe sprocket-wheel 8 ol the cranksha tt 6 aforesaid. The how 91 and itsshank 2t) constitute a swivel, the ends of said how being bearings 30for an arbor ill on which vertical center eyes 39 of a frame 33 are'lastened by set-screws 3 1 or other suitable means the frame beingshown within the confines ot' the aforesaid bow. loose on thearbontitwithin the coniiues ot' the frame is a hovel-gear erown-' .vheelin mesh with lcl preferably channel-iren beams 39, and

other bearings l for an axle 41 of wheels 42 are provided in connectionwith the beams, these lit-ants, the axle and wheels thereon constitutinga truck to which further ref-creme is made. in mesh with theC1'()\\11\\'l10l 3:) is another bevel-gear pinion 43 fast on a spindle4:4: that has antifriction hearing in a hushinf that extends through abore in the irame 33 and one of its 'trunnions. Normally loose on thespindle l-t' is a sprocket-wheel 46 corn hined with a clutch of anysuitable construction the sliding element t? of. said clutch on saidspindle being controlled by a lever 4-8 'tulrrtuaml in connection withan arm 49 of the frame 33 and arranged within convenient reach from theoperators seat 50 of the harvester. h'lountcd on the truck aforesaid isa motor in the form of a gaso lene-engine having a s1u'oclachwheel 51fast on its crankshaftand a. linlz-helt 53 connects this sprocket-wheelwith the one 46 aforesaid.

From the foregoing it. will be readily understood that the frame 35) hasfree play on a vertical axis and the swivel-how 21 has like play on ahorizontal axis, the two combining to form a universal-joint between theharvester and motor-rarrving truck to compensate for i'rregzjularitiesof surface over which said harvester and truck are traveled, and thuscramp in the gearing connecting the ll'lUtOl and the harvester machineryis, avoided, the crown-whee 35 being an idler connecting the pinions {t3and 25 to transmit, motion from one to the other.

hen ground conditions are such that: the inai-l'i-wheel of the harvestercannot perform its function as a driver for the machinery of saidharvester, as frequently happens in various localities, the powertransmission between said main wheel and cranle shaftor otherwise ofsaid imurhinery cut; out and the s 'a'octretovheel 4-6 clutched inconnection with the spindle 44. How it the motor he started the power ofsame will he exerted to orive the harvester i'i'iachinery through themedium of the transmission gearing above specified, it lacing understoodthat said motor is non-effective as a means for propulsion of theharvester and the mo tor truck.

I claim:

it. A harvester, a truck, a universai-ioint;'

recess? face over which said harvester and truck are traveled and crampin said gearing avoided 2. A harvester, clips embracing a sill of same,stems in connection with the clips, a

har fast on the stems, a truck, a universaljoint connecting the truckand said bar, motor carried by the truck, and clutch-controlled gearingconnecting the motor with the harvester machinery through said joint bywhich compensation is had for irregug larities of surface over whichsaid harvester and truck are traveled and cramp in said gearing avoided.

3. A harvester, clips embracing a Slll of same and havingtlrimhlc-extensions, stems 35 fast in the thimhles, a bar fast on thestems, a truck, a universal-joint connecting the truck and said bar, amotor carried by the truck, and clutch-controlled gearingconi'iecting-the motor with the harvester ma ge chinery through saidjoint by which compensation is had for irregularities of surface overwhich said harvester and truck are traveled and cramp in said gearing"avoided.
